Obstacles – Tree stump removal costs $160 to $350 on average.ĭrainage – Installing a French drain costs $10 to $30 per linear foot to prevent erosion and flooding near the retaining wall. Site leveling – The cost to level or regrade land is $0.40 to $2.00 per square foot. Site access – Rugged and sloped terrain or sites with limited access for delivery trucks or heavy machinery increase labor time. Builders sometimes change a wall’s planned location to avoid cutting underground utility lines.
Size – Taller retaining walls need stronger foundations and additional reinforcements.ĭesign – Complex designs, curves, and steps take more labor time.įoundation – Concrete footings cost $18 to $55 per linear foot according to the depth. Labor – Retaining wall contractors charge $33 to $90 per linear foot. Many local conditions impact the cost to build a concrete retaining wall:
